To all whom; it mayv concern:

Be it known that I, EDGAR F. HATHAWAY, a citizen ofthe United States, and. resident of WVellesley, in the county of Norfolk and,

State of lllassachusetts, have invented cer rying the tuft tubes and the yarn spool for pairs.

use in weavingtufted fabrics such .as Axminster carpets. 1 1

. The strains to which the spool and-tubes'upporting frames are subjected in their travel to and from the loom has, resulted in loosening the connections between the sus-, pension hangers and the carrier bar, thus impairing the reliability of its action and necessitating frequent replacement or re The present invention isfounded upon the principle of so constructing thetubular carrier bar which forms the backbone of the tube frame thatit is provided with integral attaching wingsso disposed andarranged as to afford a very rigid connection with the 7 suspension hangers bywhich-the bar and the yarn-spool are suspended or supported from the usual conveyor chains. To this end the invention comprises, generally speaking, a tubular carrier bar whose ends are formed with lateral or transverse integral wings adapted to lie or abut against the adjacent faces of the suspension arms or hangers and to be rigidly and firmly secured thereto preferably by detachable fastening means. This and other features of the invention will be particularly explained in the following specification and will be defined in the claims hereto annexed.

In the accompanying drawings I have illustrated several specific forms embodying the principles of this invention, in which:

Figure 1 is a front elevation, the end portion of a tube-frame embodying one form of the invention. I

Figure 2 is a cross section through the carrier bar showing the lower portion of the hanger attached thereto. a

Figure 3 is a detail showing in perspective the end of the carrier bar.

Figures 4' and 5 are details showing a modified construction of carrier bar and hanger in front elevatlon and cross section, respectively.

Figure 6 is a front elevation showing another modification. c

. F igure 7. isal perspective view showing the end of the carrier bar illustrated in F igure 6. 3 Figure 8, is a front elevation of another modification. I

Figure9 shows a perspectiveof the end of the carrier bar, shown inFigure 8. v

In the practice of this invention, accor ing to the form illustrated in Figures 1 to 3,.the main body portion 1, of the; carrier bar is oftubular construction, polygonal in cross section, and has itsf top and bottom walls formed with transversely bent wings 10, extending at substantially right angles to thelongitudinal axis of thecarrierbar so asito exposefiat outside faces againstthe inside face of the suspension hanger 2. The suspension hangerr2as actually shown in this case is made of two laminated members soldered or welded face to facehaving an upwardchain engaging extension 3, and a bearing ear 4; which receives a journalof the yarn spool 6.. Any, suitable form-of spring latch 5, maybe secured to the outer wings or members 10 lie in parallelism with the inside faces of the hangers it will be seen that these parts can rest solidly against each other and may be attached together by any suitable means, preferably by attaching screws 11 which when desired. A

In Figures 4 and 5 I have shown a modified "construction in which the suspension hanger 2 is provided with an angularly. bent arm 2?. which fits into a depression or countersunk recess formed in the end of the bottom wall of the tubular carrier bar 1, and which is rigidly but detachably united there with by an attaching screw. An attaching wing 10 extending transversely from the top wall of the tubular bar forms a companion attaching member, and there. are also provided attaching wings 12 which are inturned from the opposite side walls of the carrier bar to form additional attaching members extending at right angles to the attaching face of the suspension hanger, similar to the wings l2 of'Figure 4: but in this'case the top and bottom attaching members are omitted. V

In Figures 8 and9 are shown top and bottom attaching members 10 formed on the top and bottom walls of thecar'rier baras previously described, but in this case the side walls are provided with perforated eX- tensions or wings 14 which project endwise sufliciently to overlap the opposite side edges of the interposed suspension hanger 2, and

are then bent transversely of the longitudinal axis of thebar to form external overlapping ears through which attaching screws may be passed into the exterior face of the hanger. r

What I claim is:

I. A tuft tube frame for weaving embracingi'n its construction a suspension hanger, a tubular carrier bar of polygonal cross section having the end portions of opposite walls turned at substantially right angles to the longitudinal axis of the bar to form attaching wings adapted to rest firmly against the'adjacent face: of the hanger to which they are securely united, substantially as described. J

2. A tuft tube frame for weaving embrac .i'ngin its construction suspension hangers,

a tubular carrier bar having endwise extensrons bent transversely of the carrier bar,

; so as to lie against the adjacent opposed faces of the hangers, and means forfirmly but detachably securing the hangers'to such extensions of the carrier bar, substantially presenting flat surfaces adapted to lie in contact with the inside faces of suspension arms, and a pair of suspension arms laid against the exposed fiat faces of said attaching members and rigidly secured thereto, substantially as described.

4. A tuft tube frame for weaving embracing in its construction a suspension hanger, a tubular carrier bar of polygonalcross section whose adjacent walls are formed with integral attaching Wings at the end of the bar bent transverselythereof to lie in a plane parallel with the inside face of the suspension hanger, and means for detachably securing the attaching'members against said inside faces of the hangers, substan tially as described. y

5. A tuft tube frame for weavingembracing in its construction, a suspension hanger, a' tubular carrier bar of polygonal cross section having the end portion of its top and bottom walls bent to 'form integral transverse attaching wii'ig-s and having its opposite sidewalls also bent to form attaching wings extending substantially at right angles to the first named attachingwings, and means for securing the Wings against the face of the hangeragainst which they are disposed, substantially as described.

In witness whereof, I have subscribed the above specification. 1
